hey folks. I just recently added a bass box to my system and it introduced a bad hum to the overal main speakers... What causes this? (I'm not an electrical engineer) and how can I fix it?
more info: I have a very sensitive system... its a Jolida integrated stereo tube amp, with a Denon universal player for the source. I have a audiophile version of a BrickWall for isolated power/filter but that doesn't help with this hum at all.
Pehaps you have a ground loop. Try using a cheater plug on the power cord of the sub. This seems to be a fairly common problem (I have it too) and this is a simple fix.
